Dr. Patrick Callahan shares the wake-up call he had during his first semester of college. He believes being a doctor is more than a dream. It requires a strong work ethic, dedication, a high IQ, and a desire to help people. Do not become a doctor based on the drama of Grey’s Anatomy or the expectation to become rich or have a lot of free time. It is a very demanding profession and it has to be based on your calling to help children if you want to be a Pediatric Cardiologist like him. We at Teen Say hope his journey helps you figure out yours.
